It happened around 4:30 p.m. on I-75 South between Raccoon Valley Road and Emory Road.

The driver of the RV says he is from California and was heading to Dollywood. He says he blew a tire, but then couldn't find a safe place to pull over. As he was trying to get to the next exit, it appears friction from the tire on the pavement ignited the fire.

A member of the Rescue Squad saw the fire as he was driving by, and reported the incident.

The highway closed for a while, but has since reopened.

The driver was uninjured. He says he hasn't found his dog and cat after the incident.
